My name is Samuel Kahn. I'm a technology leader, successfully exited startup co-founder, and architect with 17+ years building cutting-edge software, growing engineering teams, and pushing technical excellence. Expert in game technology, cloud native backend, architecture and strategy. When projects need specialized expertise beyond my core focus, I bring in domain experts I've worked with for years. You get senior execution, not junior bodies.
How does fractional CTO work?
We get you to your next stage without waiting. Whether that's shipping a milestone, managing a transition, or filling gaps while you hire the right team, engagements are flexible. Short sprints or long-term partnerships, strategic guidance and hands-on execution, scaled to what your company needs right now.
What's your tech stack?
We adapt to what fits your needs best. That said, we're most experienced with: Web (React, Node.js, Python, .NET), Mobile (React Native), Games (Unreal Engine, custom engines), Cloud (AWS, Azure, GCP), plus Rust and Supabase. In the age of AI, syntax is no longer a barrier. Good architecture prevails
Where are you located?
Based in Barcelona, working remote-first with clients globally. Collaborators are generally in Europe, and we're happy to travel when it makes sense for the project.
Do you only work with game studios?
Gaming has some of the highest software complexity out there. Realtime systems, performance at scale, complex multiplayer backends. That's where we cut our teeth and built our expertise. We're excited to tackle challenges both in gaming and beyond, and have already done so across startups in AI, healthcare, and consumer apps.
